Road Erosion PotentialTown of New PaltzUlster CountyState of New York
New Paltz• Home of SUNY New
Paltz• I-87 interchange and
a bustling town • Surrounded by
countryside and farmland
Purpose• Analyze ground erosion potential on roads within the town’s
boundaries.• Allow for prioritization of repair and maintenance efforts• Save money• Better use of materials• Better road conditions
Road System
Erosion Potential
Erosion Potential (Cont.)• Obtained from National Geospatial Gateway• Original Plan• Calculate slope using DEM data from the NGG• Research what soils are most prone to erosion• Download soil types for the area• Calculate erosion potential based on combined slope and soil
types• Soil Data from NGG• Already classified erosion potential!
Moving on…
Buffer Overlay
Clipped to Erosion…• Required
definition query for each erosion class• Created 3
separate clipped buffer polygons• Merged into
one…
Single Road Erosion Overlay
Selected Roads• First done by location
intersect• Ended up with a list of
176 roads…
• Moved to visual interpretation• Determined what
general areas required the most attention
• Mohonk Rd. and surrounding side roads• St. Hwy 208• St. Hwy 32• Interstate 87 onramp• Northern Section of
Interstate 87• Jansen Rd.• South Putt Corners Rd.
